Role of urinary Neutrophil Gelatinase-Associated Lipocalin (NGAL), Monocyte Chemoattractant Protein-1(MCP-1), and Interleukin-6(IL-6) as biomarkers in pediatric patients with hydronephrosis.

OBJECTIVES: The decision to surgically intervene in a hydronephrotic kidney in children is based on many debatable guidelines, some requiring repeated ultrasounds or renal scans. Urinary proteins have the potential to reflect renal disorders and hence can be the alternatives to such scans. Here, we aim to assess the role of urinary Neutrophil Gelatinase-Associated Lipocalin, Monocyte Chemoattractant Protein-1, and Interleukin-6 (IL-6) in such patients. METHODS: Seventeen children had obstructive hydronephrosis requiring pyeloplasty (UPJO), while seven were kept on conservative management in view of non-obstructive dilation (NOD). Urine samples were measured for the three urinary proteins at the time of presentation and following pyeloplasty using commercially available ELISA kits. RESULTS: The levels of all three urinary proteins were significantly higher in patients with UPJO children compared to the NOD group. Cut-off values to differentiate obstructive from non-obstructive hydronephrosis were obtained. A significant fall in the post-operative value of urinary IL-6 was also observed. CONCLUSION: This study highlights the potentiality of urinary proteins as biomarkers in identifying children with hydronephrosis and picking out the ones with obstructive hydronephrosis who will require pyeloplasty. The drop in levels after pyeloplasty can be employed to evaluate the effectiveness of pyeloplasty when sent serially.

Refractory Congenital Chylous Ascites: Role of Fibrin Glue in its Management.

Chylous ascites is the accumulation of triglyceride-rich lymph in the abdomen. Its occurrence during the infantile period is quite rare. Congenital chylous ascites (CCA) is one, which occurs in children <3 months of age, due to maldevelopment of the lymphatic system. There is no clearly defined treatment protocol for CCA; however, the use of medium-chain triglycerides (MCT)-based diet or total parenteral nutrition (TPN) with octreotide has been successful. Failure of conservative management, however, leads to surgical exploration to deal with those leaking lymphatics. In our case, we had initially given a trial of managing the child with MCT-based diet followed by a TPN along with octreotide. However, the failure of both leads us to operate the child during which we incorporated the use of fibrin glue over the leaking mesenteric lymphatic vesicles, which ultimately led to the resolution of the chylous ascites.

Testicular remnant "nubbin" and incidental ectopic adrenal cortical rests: A case series and systematic review.

AIM: To determine whether excising a testicular remnant or nubbin is necessary and perform a systematic review of the incidental ectopic adrenal cortical rest associated with undescended testis. MATERIAL AND METHODS: A retrospective analysis of impalpable undescended testis was carried out between May 2016 and June 2019. The demographic data, intra-operative findings and histopathological diagnosis were analyzed. In conjunction with this, systematic search of PUBMED and EMBASE database was performed by using the search terms "undescended testis" AND "ectopic adrenal tissue". Data was collected for demographic characteristics, size and appearance of ectopic adrenal cortical rest and histopathology. Quantitative data has been presented as medians. Categorical variables have been presented as percentages. RESULT: We encountered 43 cases of impalpable undescended testis, out of which, nubbins were identified in 9 cases. Incidence of EACT in nubbin and impalpable UDT was 2/9 (22.22%) and 2/43 (4.7%) respectively. None of the excised nubbin had germ cells. On Systematic review, EACT associated with UDT was seen in 90/2501 (3.6%), while its association with testicular nubbin has been reported only once before in a case report. CONCLUSION: A testicular nubbin is a condition wherein no viable testicular tissue can be grossly identified in a case of impalpable testis. Even when germ cells are not found in the excised nubbin, the presence of ectopic adrenal cortical rest make them prone to later malignant transformation. Association of EACT with UDT has been consistently reported but there is scarcity of such documentation in association with testicular nubbin.
